我正在尝试使用 Proguard 来混淆我的 Android 应用程序。此外,我正在使用 IntelliJ Idea 11.1.3 构建发布签名的 APK,并在 Open Module Settings -> Facets -> Compiler -> Run Proguard 中选择了Run Proguard选项。
当我不使用 Proguard 但使用 Proguard 时,应用程序正在编译且没有任何错误,但出现以下错误
Error:[MyApp] Warning: org.apache.commons.collections.BeanMap: can't find referenced class java.beans.Introspector
Error:[MyApp] Warning: org.apache.commons.collections.BeanMap: can't find referenced class java.beans.BeanInfo
Error:[MyApp] Warning: org.apache.commons.collections.BeanMap: can't find referenced class java.beans.PropertyDescriptor
Error:[MyApp] Warning: org.apache.commons.collections.BeanMap: can't find referenced class java.beans.IntrospectionException
Error:[MyApp] Warning: there were 14 unresolved references to classes or interfaces.
Error:[MyApp] You may need to specify additional library jars (using '-libraryjars').
Error:[MyApp] Error: Please correct the above warnings first.
如何消除这些错误?
